How does the AD9375, the first broadband RF transceiver with integrated DPD, help 5G super connection?

"The 5G Topic is really too hot!" Weng Jie , the ADI RadioVerse marketing manager who flew from the US to support the ADI RadioVerseTM technology and design ecosystem update and the AD9375 conference , said with an opening. It is expected that the 5G project launched in 2020 has already risen to the height of “national idol”, and every move has attracted attention.

"Compared to 4G, 5G will have a substantial improvement in performance," Weng Jie believes that the "5G effect" should be viewed. It should also maintain a dialectical attitude. "But when this super-strong connection is reached, the customers of ADI are also Equipment suppliers have also set high demands based on power consumption and cost."

5G performance indicators

Extreme challenge is an eternal topic

Weng Jie categorizes the enormous pressures and challenges faced by customers in the face of 5G as an eternal topic on the road to innovation:

First of all, there is a surge in the types and frequency bands of radios: if the types of radios are the earliest to be based on macro base stations, now small cell and Massive MIMO are the key underlying technologies to improve network coverage and capacity, and the scale of deployment will increase dramatically. Cellular deployments have already begun in China, and more than 80% of small cells use ADI's transceiver technology ;

Second, customers still need to reduce radio size, weight and power consumption ;

Finally, accelerating time to market , who can get ahead of the market in one step means that there is an opportunity to seize more markets and thus become a market leader.

ADI RadioVerse Marketing Manager Weng Jie gave a speech at the press conference

Powered by radio design, Weng Jie believes that technology is first – the AD9375 is launched right now!

Pre-5G includes many technologies, while small cell and Massive MIMO are key underlying technologies that increase network coverage and capacity. As we all know, these two systems have high requirements on the size, weight and power consumption of the radio. In addition, both systems require high-efficiency amplifiers, which also improves the performance of digital pre-distortion (DPD). The importance is increasing day by day. As the industry's first wideband RF transceiver with integrated DPD, the AD9375 came into being in this context. - Weng Jie

When it comes to the innovation of the AD9375, Weng Jie emphasizes from the following points:

Innovative integrated DPD, perfect compatible with AD9371

ADI's AD9371 was introduced last year as a highly integrated transceiver that replaces 20+ discrete devices in a small 12mm*12mm form factor. The AD9375, based on the innovation of the AD9371, further integrates DPD, the industry's first broadband RF transceiver with integrated DPD.

In addition, the AD9375 is also characterized by its full compatibility with the pins of the AD9371. Weng Jie exemplified: "For the existing AD9371 users, if you want to use the DPD function, it is very convenient to replace the AD9375 directly, because the compatibility of the two products is perfect."

Data speak! Breakthrough intelligent system partition

“The traditional DPD solution integrated in FPGA needs to run more data channels, because in general Tx's Synthesis Bandwidth is 3 times to 5 times the signal bandwidth,” Weng Jie explained in detail: “And integrate DPD innovation into the transceiver. After the device,

First of all, save the channel of Obs Rx , just do an internal return;

Secondly, from FPGA to transceiver, Tx's Synthesis Bandwidth does not need to be up to 5 times, just one time. ”

Weng Jie further uses data to speak. "This is also the example of 2T2R. The channel of SERDES will be reduced from the previous 8 to 4, and the power consumption will be 600mW . Corresponding to 64T64R massive MIMO , the number of SERDES channels will be more. From the previous 384 to 128 , the direct benefit is a sharp reduction in power consumption of 19W ."

Power consumption superiority, AD9375 does not have "direct" competitors

As an integrated DPD product, the AD9375 has a significant power consumption advantage over the traditional DPD method. "The power consumption of traditional FPGA-based DPD solutions is usually between 1W and 2W . The DAD power consumption of the AD9375 is only 0.1W , which is basically 1/10 of the traditional DPD solution ." Weng Jie once again verified the work of the AD9375 with data. Superiority.

On the level of market competition that the industry cares about, Weng Jie also bluntly said: "In fact, the AD9375 has no direct competitors in the market, because this is the first in the industry . The existing DPD solutions are synthesized on FPGAs. Compared to these competitors, our solution can be said to have the lowest system power consumption, the smallest board area and the lowest system cost ."

Everyone collects firewood high, and the AD9375 market supports strong!

01

Cooperation with mainstream amplifier manufacturers, supporting complete test report

According to Weng Jie , ADI has cooperated with mainstream power amplifier manufacturer Skyworks and others to linearly test its power amplifier based on the DAD scheme of AD9375, and provides a complete report including DPD settings and contrast effects before and after DPD. "This will be very convenient for customers. After using these manufacturers' amplifiers, according to these reports, we know how to use the AD9375," Weng Jie added.

Launch of small cell radio reference design to accelerate customer product launch

More than that, ADI has also introduced a small cellular radio reference design based on the AD9375. Weng Jie’s scene explains, “This is a complete signal chain from JESD204B to the antenna. At the same time, it can be reconfigured to other frequency bands . Currently, this design has been sold on the RadioVerse website. We have also provided it with An evaluation kit that connects to the baseband subsystem ."

Weng Jie laughed at the scene: "The 250mW small cellular radio with the lowest power consumption and the smallest size in the market is designed to help customers improve R&D efficiency and further accelerate time-to-market with a common platform design that can be easily reconfigured to other frequency bands . "

Faced with the ultimate challenge brought by 5G super-strong connection, the AD9375 is only the “iceberg” of ADI layout, helping customers solve the problems related to radio design. The “ADI's worry and worry” is the RadioVerse ecosystem platform.

4 levels to create a " star ecosystem " focused on radio design

Committed to solving radio design challenges, RadioVerse starts with the following four levels:

First, it must be ADI's industry-leading integrated transceiver technology , which is the core of RadioVerse;

Second, in addition to core technologies, ADI has a technical support ecosystem that encompasses a variety of evaluation platforms, software, hardware, documentation, and reference designs;

Thirdly, the close cooperation with third-party partners also allows RadioVerse to provide customers with a "better than better" design;

Finally, RadioVerse will provide insights, technical support and roadmap planning advice for the relevant market.

Multi-domain coverage of RadioVerse "bring your own traffic"

According to Weng Jie , RadioVerse has more than 250,000 unique visitors since its launch . " Considering that we are a B2B market for the industry, this number is already very amazing." Weng Jie 's words are full of joy, "The AD9361 and AD9371 are now products that are firmly on the ADI Web Search Hot List."

At present, RadioVerse not only achieves multi-domain coverage of small cell, large-scale MIMIO, defense application, wireless image transmission, SDR and IoT applications , but also has a wide range of customers to visit, from different industries of various scales, to industry giants, small to startup. . “ This also continues to drive ADI to discover new customers and discover new application areas, so that the RadioVerse ecosystem can further feed back to a larger customer base and a wider range of applications ,” Weng Jie saw more positive.

In short, ADI hopes to establish RadioVerse as a "one-stop solution" in the field of radio design . We also hope that customers will come to RadioVerse from the time they first make products and roadmaps. From chip to the entire system solution, we all hope that customers can solve their problems on RadioVerse. - Weng Jie

I believe that many fans are more excited about the launch of the AD9375 and the update of RadioVerse, and look forward to the next move of ADI. According to Weng Jie , "The next generation of products is under development and is planned to be launched next year. By then, the bandwidth will increase and expand. Now with a 100MHz bandwidth range , of course, a significant increase in performance is also essential."
